TECHNICAL FIELD

The concepts and technologies disclosed herein generally relate to wireless telecommunications. More specifically, the concepts and technologies disclosed herein relate to hybrid network-based and device-based intelligent radio access control in wireless telecommunications networks.

BACKGROUND

In recent years, mobile telecommunications carriers have experienced a dramatic increase in traffic on their networks, and this trend will likely continue. This increase in traffic has been caused in part by the increased adoption of smartphones and other devices that rely on mobile telecommunications networks, and the migration of many customers from utilizing landline telecommunication services to utilizing mobile telecommunication services for their communications needs. To meet the demands of higher traffic and to improve the end user experience, mobile telecommunications carriers are examining mechanisms by which to improve network efficiency, network capacity, and the end user experience, while keeping operational costs at a level conducive to maintaining competitive rates for the services they provide.

Referring now to the drawings, in which like numerals represent like elements throughout the several figures, example aspects of hybrid network-based and device-based intelligent radio access control will be presented.

Referring now to FIG. 1, aspects of an illustrative operating environment 100 for various concepts disclosed herein will be described. It should be understood that the operating environment 100 and the various components thereof have been greatly simplified for purposes of discussion. Accordingly, additional or alternative components of the operating environment 100 can be made available without departing from the embodiments described herein.

The operating environment 100 shown in FIG. 1 includes a mobile device 102 that is configured to connect to and communicate with a plurality of radio access networks (“RANs”) 104A-104N (hereinafter, at times, referred to collectively or generically as “RANs 104”) for voice and/or data communications between the mobile device 102 and one or more other mobile devices, computers, servers, networking devices, and/or networks (not shown). Although in the illustrated example, the mobile device 102 is shown as being in communication with three RANs, the mobile device 102 may be in communication with any number of RANs, and, at times, may be in simultaneous communication with multiple RANs.

The mobile device 102 may be a cellular phone, a feature phone, a smartphone, a mobile computing device, a tablet computing device, a portable television, a portable video game console, or any other computing device that is configured to connect to and communicate with one or more of the RANs 104 via one or more radio access components. In some embodiments, the mobile device 102 includes an integrated or external radio access component that facilitates wireless communication with one or more of the RANs 104. The radio access component may be a cellular telephone that is in wired or wireless communication with the mobile device 102 to facilitate a tethered data connection to one or more of the RANs 104. Alternatively, the access component includes a wireless transceiver configured to send data to and receive data from one or more of the RANs 104 and a universal serial bus (“USB”) or another communication interface for connection to the mobile device 102 so as to enable tethering. In any case, the mobile device 102 can wirelessly communicate with one or more of the RANs 104 over a radio/air interface in accordance with one or more radio access technologies (“RATs”). The mobile device 102 may also initiate, receive, and/or maintain voice calls with one or more other voice-enabled telecommunications devices such as other mobile devices or landline devices (not shown). The mobile device 102 may also exchange Short Message Service (“SMS”) messages, Multimedia Message Service (“MMS”) messages, email, and/or other messages with other devices (not shown).

Each of the RANs 104 may operate in accordance with one or more mobile telecommunications standards including, but not limited to, Global System for Mobile communications (“GSM”), Code Division Multiple Access (“CDMA”) ONE, CDMA2000, Universal Mobile Telecommunications System (“UMTS”), Long-Term Evolution (“LTE”), Worldwide Interoperability for Microwave Access (“WiMAX”), other 802.XX technologies, and/or the like. Each of the RANs 104 can utilize various channel access methods (which may or may not be used by the aforementioned standards) including, but not limited to, Time Division Multiple Access (“TDMA”), Frequency Division Multiple Access (“FDMA”), CDMA, wideband CDMA (“W-CDMA”), Orthogonal Frequency Division Multiplexing (“OFDM”), Space Division Multiple Access (“SDMA”), and/or the like to provide a radio/air interface to the mobile device 102. Data communications can be provided in part by the RANs 104 using General Packet Radio Service (“GPRS”), Enhanced Data rates for Global Evolution (“EDGE”), the High-Speed Packet Access (“HSPA”) protocol family including High-Speed Downlink Packet Access (“HSDPA”), Enhanced Uplink (“EUL”) or otherwise termed High-Speed Uplink Packet Access (“HSUPA”), Evolved HSPA (“HSPA+”), LTE, and/or various other current and future wireless data access technologies.

Each of the RANs 104 may be a GSM RAN (“GRAN”), a GSM EDGE RAN (“GERAN”), a UMTS Terrestrial Radio Access Network (“UTRAN”), an E-UTRAN, any combination thereof, and/or the like. As such, each of the RANs 104 may include one or more base transceiver stations (“BTSs”), one or more Node Bs, one or more eNodeBs, and/or the like. As used herein, a “base station” refers to a radio receiver and/or transmitter (collectively, transceiver) that are configured to provide a radio/air interface by which one or more mobile devices, such as the mobile device 102, can connect to a network. Accordingly, base station encompasses all the aforementioned networking nodes that are capable of provide a radio/air interface regardless of the technologies utilized to do so. Moreover, a base station can be in communication with one or more antennas, each of which may be configured in accordance with any antenna design specifications to provide a physical interface for receiving and transmitting radio waves to/from a network.

The RANs 104 can be part of one or more mobile telecommunications networks. As used herein, a mobile telecommunications network includes one or more RANs and a wireless wide area network (“WWAN”), which may, in turn, include one or more core networks such as a circuit-switched core network (“CS CN”), a packet-switched core network (“PS CN”), and/or an IP multimedia subsystem (“IMS”) core network. The WWAN can utilize one or more mobile telecommunications technologies, such as those described above, to provide voice and/or data services via one or more RANs to one or more radio components of one or more mobile devices, such as the mobile device 102. Moreover, a mobile telecommunications network can provide a connection to the Internet or other WAN so that the mobile device 102 can access Internet content such as Websites, streaming media, online video games, downloadable content, and the like.

In addition to or as an alternative to operating in accordance one or more mobile telecommunications standards, one or more of the RANs 104 may operate in accordance with one or more Institute of Electrical and Electronic Engineers (“IEEE”) 802.11 standards such as IEEE 802.11a, 802.11b, 802.11g, 802.11n, and/or future 802.11 standard (referred to herein collectively as “WI-FI”). Draft 802.11 standards are also contemplated. A WI-FI network may be implemented utilizing one or more wireless WI-FI access points. In some implementations, one or more of the wireless WI-FI access points is a mobile device or other computing device that functions as a WI-FI hotspot. In some implementations, the mobile device 102 connects to a WI-FI network facilitated in part by one or more of the RANs 104 via one or more secure connections, each of which may utilize an encryption technology such as, but not limited to, WI-FI Protected Access (“WPA”), WPA2, Wired Equivalent Privacy (“WEP”), and/or the like. Moreover, a WI-FI network can provide a connection to the Internet or other WAN so that the mobile device 102 can access Internet content such as Websites, streaming media, online video games, downloadable content, and the like.

As used herein, a RAT can refer to any mobile telecommunications standard or draft standard thereof, any IEEE 802.11 standard or draft standard thereof, or any other technology by which a mobile device, such as the mobile device 102, can wirelessly access a network, such as one or more of the RANs 104.

The operating environment 100 also includes a RAT selection system 106. The RAT selection system 106 is configured to cooperate with one or more mobile devices, such as the mobile device 102, to enable an intelligent multi-radio access control that can select one or more RATs that are best-suited for the mobile device(s) based upon network conditions, policies, user profiles, local device information, and/or other information. More particularly, the RAT selection system 106 is configured to generate a list of networks based upon network conditions, policies, user profiles, and/or other information. In some embodiments, the list of networks includes a prioritized list of networks. The RAT selection system 106 is also configured to provide the list of networks to the mobile device, which uses local device information to select a network from the list and connect to the selected network. In this manner, the RAT selection system 106 can cooperate with the mobile devices, such as the mobile device 102, to steer traffic to various networks operating in accordance with different RATs to improve user experience, especially in network traffic congested areas, and to efficiently leverage network resources for mobile telecommunications and WI-FI networks. These and other aspects of the RAT selection system 106 and the mobile device 102 will be described in greater detail below.

In the illustrated example, the RAT selection system 106 is configured to receive load information 108A-108N (hereinafter, at times, referred to collectively or generically as “load information 108”) from the RANs 104, and utilize the load information 108 at least in part to determine which RAN(s) of the RANs 104 the mobile device 102 should connect to. In addition to the load information 108, the RAT selection system 106 can utilize one or more policies 110 received from a policy server 112 and/or one or more user profiles 114 received from a user profile server 116 in determining which RAN(s) of the RANs 104 the mobile device 102 should connect to. The RAT selection system 106 can generate a network selection list 118 that includes an identification of the RAN(s) and, potentially, one or more policy rules to use these RANs that the mobile device 102 should connect to, and can send the network selection list 118 to the mobile device 102. The mobile device 102 can connect to one or more of the RANs 104 based upon the RAN(s) identified in the network selection 118 and local device information. The mobile device 102 can also utilize local device information such as, but not limited but not limited to, mobility state information, performance measurement information, battery utilization information, channel quality information, application(s), and/or a user override selection, in determining which of RAN(s) of the RANs 104 to connect to.

The network selection list 118 can specify an order in which to select the RANs 104. It should be understood that the order in which the RAT selection system 106 specifies RANs to be selected is not intended to imply that the mobile device 102 must select each of the RANs, but that the RAT selection system 106 has specified the order as a preferred order or priority order in which to select the RANs based upon information available to the RAT selection system 106. The local device information can aid the mobile device 102 in selecting a RAN from the network selection list 118. In some implementations, for example, the selected RAN is the most preferred or highest priority RAN on the network selection list 118. In some other implementations, for example, the selected RAN is the least preferred or lowest priority RAN on the network selection list 118. Other implementations may include the mobile device 102 selecting a RAN from the network selection list 118 that is between a most preferred or highest priority RAN and a least preferred or lowest priority RAN based upon the local device information. Accordingly, the network selection list 118 is intended to provide a list of recommendations to the mobile device 102 for making a determination as to which RAN to connect to, while the mobile device 102 is capable of weighting the recommendations provided in the network selection list 118 with the local device information to determine which RAN to select.

In some embodiments, the load information 108 includes historic network load information. Historic network load information is used herein to describe data obtained by the RAT selection system 106 based upon network load experienced by one or more of the RANs 104 in the past or otherwise in non-real-time. In some embodiments, historic network load information is utilized by the RAT selection system 106 to identify one or more network load trends experienced by a RAN over a specified period of time. This trending network load information can be useful to the RAT selection system 106 to predict times during which network load is favorable or not to support communications from additional mobile devices, such as the mobile device 102.

In some other embodiments, the load information 108 includes current network load information. Current network load data is used herein to describe network load data that is obtained by the RAT selection system 106 based upon a network load experienced by one or more of the RANs 104 in real-time or near real-time. Real-time, in this context, is the actual time during which a network load is experienced by one or more of the RANs 104. Near real-time, in this context, is the actual time during which a network load is experienced by a RAN plus a delay on the order of seconds, minutes, or some order of magnitude thereof, for example.

What constitutes near-real time network load information versus historic network load information can be defined by the owner and/or operator of the RAT selection system 106, a service provider providing service via one or more of the RANs 104, and/or another entity. It should be understood that real-time network load information associated with a real-time network load information of one or more of the RANs 104 and near real-time network load information associated with a near real-time network load of one or more of the RANs 104 might be received by the RAT selection system 106 with delay caused by latency and/or other network phenomena. Moreover, this delay may increase with the additional time needed to provide the load information 108 to the RAT selection system 106.

In the illustrated embodiment, the policies 110 are stored in a policy database 120 with any number of other policies. The policy database 120 may be separate from and in communication with the policy server 112 as in the illustrated embodiment, or alternatively may be provided as part of the policy server 112. In any case, the policy server 112 can obtain the policies 110 from the policy database 120 and send the policies 110 to the RAT selection system 106 in response to a request received from the RAT selection system 106, periodically, or in response to an event, such as a change to one or more of the policies 110.

As used herein, the term “policy” refers to one or more settings, one or more configurations, one or more rules, and/or the like that define, at least in part, one or more courses or methods of action in light of one or more conditions to be used in a determination made by the RAT selection system 106 regarding which RAN(s) of the RANs 104 the mobile device 102 and/or other mobile devices should connect to. In some embodiments, a policy includes one or more rules that specify one or more if-then conditions by which to handle a particular situation, such as redirecting network traffic based upon network load experienced by one or more of the RANs 104 and reported to the RAT selection system 106 as part of the load information 108, applications, time-of-day, locations, combinations thereof, and the like. In some other embodiments, a policy includes one or more matrices of cause and effect conditions, tables of actions, or the like for responding to or otherwise dealing with certain stimuli, such as network conditions evidenced by the load information 108, the user profiles 114, and/or other stimuli.

Also in the illustrated embodiment, the user profiles 114 can be stored in a profile database 120 with any number of other user profiles. The profile database 120 may be separate from and in communication with the user profile server 116 as in the illustrated embodiment, or alternatively may be provided as part of the user profile server 116. In any case, the user profile server 116 can obtain the user profiles 114 in response to a request received from the RAT selection system 106, periodically, or in response to an event, such as a change to one or more of the user profiles 114.

As used herein, the term “user profile” refers to a collection of data associated with a user that accesses one or more of the RANs 104 via a device such as the mobile device 102. A user in this context refers to an individual or other entity. A user profile can define information regarding a service agreement between a user and one or more service providers that provide telecommunications service, at least in part, via one or more of the RANs 104. The service agreement may include terms of service for pre-paid and/or post-paid service. The service agreement may include terms of roaming agreements between two or more mobile telecommunications carriers. The service agreement may define a service tier for the user. A service tier may establish a priority for a user in regard to utilizing network resources to connect to one or more of the RANs 104 via the mobile device 102.

In some embodiments, the RAT selection system 106 is owned and/or operated by an owner and/or operator of one or more of the RANs 104. In some embodiments, the policy server 112 is owned and/or operated by an owner and/or operator of one or more of the RANs 104. In some embodiments, the user profile server 116 is owned and/or operated by an owner and/or operator of one or more of the RANs 104. In some embodiments, the RAT selection system 106 includes the policy server 112 and/or the user profile server 116.

It should be understood that some implementations of the operating environment 100 include multiple mobile devices 102, multiple RAT selection systems 106, multiple policy servers 112, multiple policy databases 118, multiple user profile servers 116, and/or multiple profile databases 120. Moreover, the RAT selection system 106, the policy server 112, and/or the user profile server 116 may be provided as part of one or more distributed computing systems. Thus, the illustrated embodiment should be understood as being illustrative, and should not be construed as being limiting in any way.

Turning now to FIG. 2, a block diagram illustrating additional aspects of the RAT selection system 106 and the mobile device 102 will be described, according to an illustrative embodiment. In the illustrated embodiment, the RAT selection system 106 is configured to receive the load information 108, the policies 110, and the user profiles 114, utilize at least some of this information to determine which of the RANs 104 the mobile device 102 should connect to, and provide the selection of one or more of the RANs 104 to the mobile device 102 in the network selection list 118. The illustrated RAT selection system 106 includes a network decision engine 200 and a network database repository 202, both of which will now be described in greater detail.

The network decision engine 200 utilizes the load information 108, the policies 110, the user profiles 114, or any combination thereof, to make a determination regarding which of the RAN(s) 104 the mobile device 102 should connect to. In some embodiments, the network decision engine 200 is an application program that includes computer-executable instructions that, when executed by one or more processors of the RAT selection system 106, cause the RAT selection system 106 to analyze the load information 108, the policies 110, and the user profiles 114, alone or in any combination, to select one or more of the RANs 104, and instruct the mobile device 102, and possibly one or more other target devices, to connect to the selected RAN(s) via the network selection list 118.

The network database repository 202 includes trending network load information 204 for one or more of the RANs 104 and current network load information 206 for one or more of the RANs 104. In some embodiments, the trending network load information 204 is received from one or more of the RANs 104 via periodic network load updates, such as every fifteen minutes or other time period. In some embodiments, the current network load information 206 is received from one or more of the RANs 104 in an event-driven network load update. An event-driven network load update may be triggered at a RAN due to the network load experienced by that RAN meeting or exceeding a pre-defined network load threshold. In some embodiments, the RAT selection system 106 can request the current network load information 206 if needed by the network decision engine 200 to select one or more of the RANs 104. The network load information 108 can include network load information received via periodic network load updates and event-driven network load updates. It should be understood, however, that some implementations may utilize only the trending network load information 204 or only the current network load information 206. It should also be understood that although the network database repository 202 is shown as being included in the RAT selection system 106, the network database repository 202 may be external to and in communication with the RAT selection system 106. In these implementations, the network database repository 202 may receive the load information 108 and provide the load information 108 to the RAT selection system 106 via one or more wired or wireless communication links.

The mobile device 102 illustrated in FIG. 2 includes an operating system 208, a device-based network decision manager 210, a network connection manager 212, one or more radio access components 214, and local device information 216. The operating system 208 is a program for controlling the operation of the mobile device 102. The operating system 208 can include a member of the SYMBIAN OS family of operating systems from SYMBIAN LIMITED, a member of the WINDOWS MOBILE OS and/or WINDOWS PHONE OS families of operating systems from MICROSOFT CORPORATION, a member of the PALM WEBOS family of operating systems from HEWLETT PACKARD CORPORATION, a member of the BLACKBERRY OS family of operating systems from RESEARCH IN MOTION LIMITED, a member of the IOS family of operating systems from APPLE INC., a member of the ANDROID OS family of operating systems from GOOGLE INC., and/or other operating systems. These operating systems are merely illustrative of some contemplated operating systems that may be used in accordance with various embodiments of the concepts and technologies described herein and therefore should not be construed as being limiting in any way.

The device-based network decision engine 210 utilizes the network selection list 118 and the local device information 216 to determine which network(s) the mobile device 102 should connect to. In some embodiments, the device-based network decision engine 210 is an application program that includes computer-executable instructions that, when executed by one or more processors of the mobile device 102, cause the mobile device 102 to analyze the network selection list 118 and the local device information 216 to select one or more of the RANs 104, and to instruct the mobile device 102, and more particularly, the network connection manager 212, to connect to the selected RAN(s).

The network connection manager 212 can be configured to manage all or a portion of the network connections available to the mobile device 102 at a given time, including, for example, connections established via one or more WI-FI radios and/or one or more cellular radios of the mobile device 102, such as one or more of the radio access components 214. In some embodiments, the network connection manager 212 is included as part of the operating system 208 and/or another application stored on the mobile device 102 such as the device-based network decision engine 210.

The illustrated local device information 216 includes mobility state information 218, one or more user rules 220, one or more applications 222, performance measurement information 224, battery utilization information 226, and channel quality information 228. These types of local device information are merely illustrative of some contemplated information that may be used in accordance with various embodiments of the concepts and technologies described herein for selecting a network and therefore should not be construed as being limiting in any way.

The mobility state information 218 can include the speed at which the mobile device 102 is currently moving, a movement pattern of the mobile device 102, and/or any other information associated with movement or non-movement of the mobile device 102. The mobility state information 218 may be obtained by an accelerometer, a Global Positioning System (“GPS”) component, and/or other motion sensor or component of the mobile device 102. The mobility state information 218 can be utilized by the device-based network decision engine 210 to determine if it is appropriate for the mobile device 102 to connect to a network given the movement or non-movement of the mobile device 102. For example, if the mobility state information 218 indicates that the mobile device 102 is moving at 60 miles per hour and a WI-FI network is available to the mobile device 102, the device-based network decision engine 210 can determine to forgo connecting to the WI-FI network based upon the relatively fast movement of the mobile device 102 and the prediction that the mobile device 102 will not be within range of the WI-FI network for a sufficient amount of time to handle voice and/or data communications between the mobile device 102 and the WI-FI network. Alternatively, for example, if the mobility state information 218 indicates that the mobile device is stationary and a WI-FI network is available to the mobile device 102, the device-based network decision engine 210 can determine to connect to the WI-FI network based upon the stationary state of the mobile device 102 and the prediction that the mobile device 102 will be within range of the WI-FI network for a sufficient amount of time to handle voice and/or data communications between the mobile device 102 and the WI-FI network.

The user rule(s) 220 can include rules specified by or for a user of the mobile device 102 regarding network selections. For example, a user rule may specify an override selection of a network that should be selected if the network is available. An override selection can be conditional.
